Thats cool DG.. Flu bug sucks. Hope you feel better soon..

Purchased the Omega unit like Chris.. And bought diodes & relays today.. And preparing to install on Saturday.. My questions were about installing convenience features, as the lock/unlock remote installation instructions are documented well in this thread...

Your response lets me know that parking light connection is possible at the tail lamp (doing a trunk install). I do have wiring diagrams but Im not sure which wires to tap into: Positive OR Negative wire, relay wire or trigger wire. I want figure the wiring out before I start. Hopefully, I can finish this on Sat..

Heres some horn connection info: http://www.the12volt.com/carsecurity/page3.asp#hn
And heres the wiring diagrams site for a 91 300SE (site appears to be up only during the day):

Ive been reading up on installing diodes. Now, Im more confused.. We need a diode writeup for our cars..
The diode will stop leakage and I understand how. But you install it depending on the flow of current + & -...
Well for our door locks, the single line trigger is both positive & negative depending on the lock position.. Thus, my confusion..
